Well, it's not so much "more efficient use of RAM" but "capable of using more RAM." The Intel 32-bit architecture cannot address more than 4 Gb directly. There are indirect methods to do so, but they are a bit tricky. I don't know how Apple managed the issue, but in the Windows world at least, Microsoft opted to not allow consumer-level machines and low-end servers (which, back in the days before AMD64 and E64T extensions, didn't even have enough sockets for more than 4Gb anyway) to use those indirect methods. Rule of the thumb: if you have less than 4Gb of RAM, 64-bit mode won't make much of a difference. If you have 4Gb, depending on a number of factors, you may see some more free RAM. If you have more than 4Gb, you probably should be using 64-bit mode. -- MCBastos This message has been protected with the 2ROT13 algorithm.
